Therapeutic Effects of AICAR and DOX Conjugated Multifunctional Nanoparticles in Sensitization and Elimination of Cancer Cells via Survivin Targeting

Purpose Resistance to chemotherapy is one of the major problems facing current cancer research. Enhancing tumor cell response to anticancer agents increases chemotherapeutic effectiveness. We have recently addressed this issue and reported on producing multifunctional nanoparticles (Fe3O4@SiO2(FITC)-FA/AICAR/DOX) aiming to overcome chemoresistance with synergetic effect of AICAR and DOX. In the present study, we demonstrated that these nanoparticles not only show enhanced cellular uptake and cytotoxic effect but can also show enhanced pro-apoptotic and anti-proliferative effects in five different tumor-derived cell lines (A549, HCT-116, HeLa, Jurkat and MIA PaCa-2).
